11.4.3 Radio receiver unit: starting teach-in
The teaching process is started by pressing the teach
button on the radio receiver unit. The teaching process
is automatically terminated after approximately 15 min-
utes. If you also replaced the outside temperature sen-
sor/transmitter before the radio controller, it may be
that the process you initiated for activating the outside
temperature sensor/transmitter is still active. If it is, the
green LED on the radio receiver unit will be flashing.
> If the green LED on the radio receiver unit is flash-
ing, press the teach button to stop the teaching
process. The green LED should then stop flashing
but remain lit.
> Press the teach button to restart the teaching proc-
ess. The green LED will start flashing.
